In March 2020 Yukon decided to switch its clocks for the last time and to remain on Pacific Daylight Time (PDT). The GMT/UTC time difference or offset is set to be GMT minus 7 hours (GMT-7), seven hours behind GMT.
When clocks go back in USA and Canada according to current rules, Yukon will stay on PDT (source: Yukon government press release)
Pacific Standard Time ( PST ) = GMT-8
Pacific Daylight Time (PDT ) = GMT-7
Yukon is in the Pacific Time Zone in Canada, which is 8 hours behind Greenwich Mean Time ( GMT-8 ).
Like most provinces in Canada, Daylight Saving Time is observed in Yukon, where the time is shifted forward by 1 hour, resulting in a 7 hours difference behind Greenwich Mean Time ( GMT-7 ).
After the Summer months the time is shifted back by 1 hour resulting in the normal 8 hours difference behind GMT.
